Law-enforcement officials told NBC News that several students were attacked with a large knife. The campus was put on lockdown early Monday morning after reports of an active shooter. The lockdown was lifted at 11:30 a.m., and the university reports that the "scene is now secure."

It is unclear whether the suspect or suspects have been detained, but the news station is reporting that two men were seen being led away in handcuffs.

While there has been no official word about what took place, one student told NBC News that she saw a car plow into a crowd of people who'd evacuated a building.

"This car just swerved and ran into a whole group of people," Nicole Kreinbrink told the news station. "It hit a cop really bad. All these people were running and screaming and yelling."

Another student told NBC News that he heard gunfire.

"I heard gunshots from my dorm, probably six or seven," said Stephen Yunker, 18, a freshman who lives a few blocks from where the incident occurred.
